Strap for Sixties Chronograph Stainless Steel / Glacier Blue / Pin / Annual Edition

The lug width of the Sixties is exactly 20mm. This dimension is fixed for the model and is measured from the inside of one lug to the other using a digital calliper. It is essential to verify this measurement before purchasing a compatible strap to avoid fitting issues.

The best strap depends on intended use. For formal occasions, we recommend natural alligator or Japanese shell cordovan, which dialogue elegantly with the satin-brushed steel case. For daily wear, vegetable-tanned calf leather offers evolving patina and durability. For sports or casual wear, a NATO 2x2 or FKM rubber ensures practicality without aesthetic compromise.

Strap changing is performed by extracting the spring bar from the watch case lugs using a dedicated tool. The spring-loaded bar keeps the strap anchored. A professional at Casati Milano can perform this operation with precision. If executed personally, use a dedicated spring bar remover to avoid case damage.

Yes, aftermarket straps measuring 20mm lug width are fully compatible with the Sixties. Milano Straps offers bespoke straps in various materials—alligator, calf, NATO, rubber—specifically crafted for this lug width. The artisanal construction quality ensures durability and comfort identical to original factory straps.

A quality leather strap, handcrafted, typically lasts 5-7 years with daily wear, or 8-10 years with moderate use. Longevity depends on the tanning method (vegetable-tanned ages better), UV and moisture exposure, and maintenance frequency. Shell cordovan, owing to its robustness, can reach 10+ years of service.
